DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insulation design.
“Double insulation” means that two physically separated insulation systems have been used to
insulate the electrically conductive materials connected to the power supply from the outer frame
handled by the operator. Therefore, either the symbol “ ” or the words and “Double insulation”
appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in wet
environments.
To keep the double insulation system effective, follow these precautions:
* Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power
tool, and only genuine HITACHI replacement parts should be installed.
* Clean the exterior of the power tool only with a soft cloth moistened with soapy water and dry
thoroughly.
* Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may
dissolve.

9. Confirm the tool’s power cord is not damaged.
Repair or replace the power cord if an inspection indicates that it is damaged
10. Eye protection
Always wear eye protection with side shields that meets the requirements of ANSI Standard
Z87.1. Ordinary eyeglasses do not provide adequate protection because they do not contain
impact resistant safety glass.
WARNING: Operating the tool without wearing proper eye protection may
result in serious injury.
11. Electric brake
This tool is equipped with an electric brake which will typically stop the blade within 5
seconds after the trigger switch is released.
Occasionally, there will be a delay in the brake engaging which will result in a longer blade
stopping time. On rare occasions, the brake may not engage at all and the saw blade will
coast to a stop.
If the brake fails to engage frequently, depress and release the trigger switch to turn the tool
on and off4 or 5 times. If the brake still does not engage, have the tool serviced at a Hitachi
authorized service center.

Always confirm that the saw blade has completely stopped before raising it from the
workpiece.
The brake is not a substitute for a properly functioning lower guard. Check the function of
the lower guard before each use. Serious personal injury may occur if the lower guard does
not move smoothly and cover the blade properly.
WARNING: Please be aware of the reaction of the Motor Head (Fig.1) when
the brake is activated. Braking causes the Motor Head to jerk
downward and the user should be prepared for this reaction,
especially when the trigger switch is released before the blade is
completely down. Failure to be familiar with, and prepared for, the
operational characteristics of the tool may cause serious injury.
AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC
POWER SOURCE, CHECK THE OPERATION OF THE TOOL AS FOLLOWS:
12. Trial Run
After confirming that no one is standing behind, the power tool start and confirm that no
operating abnormalities exist before attempting a cutting operation.
13. Inspect the rotating stability of the saw blade.
For precise cutting, rotate the saw blade and check for deflection to confirm that the blade
is not noticeably unstable; otherwise vibrations might occur and cause an accident.

Table inserts are installed on the turntable. When shipping the tool from the factory, the
table inserts are so fixed that the saw blade does not contact them. The burr of the bottom
surface of the workpiece is remarkably reduced, if the table insert is fixed so that the gap
between the side surface of the table insert and the saw blade will be minimum. Before
using the tool, eliminate this gap in accordance with the following procedure.
